Purpose: To evaluate the intraocular pressure (IOP)-lowering performance and safety of an ab interno gelatin stent (XEN 45 Gel Stent, Allergan plc, Irvine, California, USA), a minimally invasive glaucoma surgery device, in refractory glaucoma.
Design: Single-arm, open-label, multicenter clinical study.
Methods: Following mitomycin C pretreatment, the stent was placed ab interno in patients who failed prior filtering/cilioablative procedure or had uncontrolled IOP on maximum-tolerated medical therapy, with medicated IOP ≥20 and ≤35 mm Hg and visual field mean deviation ≤-3 dB.
Purpose: To evaluate a screening protocol for detection of individuals with a higher risk of chronic open angle glaucoma for which a complete glaucoma evaluation is indicated.
Patients And Methods: African Americans over 40 years of age in New Haven, CT. In the screening phase, volunteers filled out a questionnaire and underwent measurements of visual acuity, intraocular pressure (IOP) with a Tono-Pen and visual field with Frequency Doubling Technology.
Purpose: To evaluate variables associated with failure to access free eye care after participating in glaucoma screening.
Design: Review of responses to a survey completed by participants during glaucoma screening.
Participants: Two hundred seventy-three surveys completed by participants of African descent during screening.
Glaucoma patients present a unique set of challenges to physicians performing corneal refractive surgery. Corneal thickness, which is modified during corneal refractive surgery, plays an important role in monitoring glaucoma patients because of its effect on the measured intraocular pressure. Patients undergo a transient but significant rise in intraocular pressure during the laser-assisted in situ keratomileusis (LASIK) procedure with risk of further optic nerve damage or retinal vein occlusion.

Patients And Method: : Retrospective review of a series of patients who underwent bleb revision for hypotony maculopathy (IOP less than 6 mm Hg and loss of two or more lines of central vision) following trabeculectomy. Bleb revision included excision of avascular bleb tissue, dissection posteriorly between conjunctiva and Tenon's capsule, and advancement and suturing of the conjunctiva at the limbus.
